Description

L-Kynurenine Sulfate is a high-purity, standardized salt form of the essential tryptophan metabolite, L-Kynurenine. This compound is critical for research and development in neuroscience, immunology, and metabolic studies due to its role as a key intermediate in the kynurenine pathway. It is primarily utilized by pharmaceutical R&D laboratories, academic research institutions, and diagnostic manufacturers for biochemical research, assay development, and as a reference standard.

Application

• Biochemical Research: Used as a critical precursor and reference standard in studies of the kynurenine pathway, which is implicated in neurological disorders, immune response, and inflammation.
• Pharmaceutical Development: Serves as an intermediate or starting material in the synthesis of novel neuroactive compounds and potential therapeutic agents targeting metabolic pathways.
• Diagnostic Reagent Manufacturing: Employed in the formulation of calibration standards and reagents for clinical diagnostic kits measuring tryptophan metabolism markers.
• Cell Culture & In Vitro Studies: Applied in cell-based assays to modulate cellular metabolism and study the effects of kynurenine pathway activation or inhibition.
• Metabolomics & Analytical Reference: Acts as a high-purity certified reference material (CRM) for accurate quantification in LC-MS, HPLC, and other analytical techniques.
